Conceptual Design of 1-T/360-mm Dry Wound Conduction Cooled MgB₂ Magnet for Long Term Operation

Conceptual design of a conduction-cooled MgB2 magnet with an inner diameter of 360 mm and a center magnetic field of 1 T is presented. The magnet is designed as part of the magnet development activities to carry out the feasibility study and further, to demonstrate the applicability of the MgB2 magnet in wide industrial applications which can be supported by the long-term operational data showing the robustness of the magnet. To achieve the goal of long-term robust magnet operation, mechanical design considering the react-and-wind conductor and design aspects of magnet stability and protection are considered. Due to the dry wound winding configuration, a detect-and-activate-heater technique is applied to the magnet as an active magnet protection.
